India's power sector reported strong results in H1 FY27 as electricity demand surged by over 10%. While NTPC and storage-focused firms saw profit gains from higher usage and rising spot market prices, the industry faces ongoing risks from low coal inventory and volatile weather conditions.
The first half of fiscal year 2027 has been a period of significant activity for the Indian power sector, with companies reporting strong financial performance supported by a sustained increase in electricity consumption. Driven by persistent heatwaves, overall electricity demand in India grew by more than 10% year-on-year during this period. This rise in demand pushed peak power consumption to record levels, with the national grid handling loads between 269 and 271 GW at the season's high.
Major utility players have been the primary beneficiaries of this consumption trend. NTPC, for instance, posted a 25.71% increase in its consolidated profit after tax for H1 FY27. This growth was fueled by elevated thermal plant load factors, as power plants were pushed to operate at higher capacities to meet the continuous cooling load from residential and industrial consumers. The reliance on thermal power remained high, partly because a below-average monsoon season reduced the output from hydroelectric power stations.
Companies with a presence in the short-term power market also saw their revenue per unit improve significantly. The Indian Energy Exchange (IEX) reported a 46% year-on-year increase in average electricity prices on its day-ahead market during the second quarter of the fiscal year, with rates rising sharply in September. This volatility in spot prices allowed firms like JSW Energy and Adani Power to capture better margins for the electricity they sold outside of long-term contracts. Furthermore, companies integrating newer technologies, such as ACME Solar, demonstrated the value of diversification. ACME Solar reported a 133.5% jump in net profit for the second quarter, largely by utilizing battery energy storage systems to supply power during peak demand hours when prices are highest.
Despite the positive earnings trajectory, the sector continues to navigate operational hurdles. One of the primary monitorables for investors is the status of coal inventory at thermal power plants. Current stocks have often hovered around 6 days of consumption, significantly lower than the recommended safety levels of 19 to 20 days. This creates a supply-side risk, as any disruption in coal logistics or mining could limit the ability of utilities to meet demand surges. Additionally, the industry's heavy dependence on weather patterns, often linked to El Nino effects, makes demand forecasting difficult and increases the likelihood of utilities having to purchase expensive power from the spot market to fulfill their commitments.
Looking ahead, the focus for the sector remains on capacity addition and the integration of energy storage. Investors will likely track how utilities manage their fuel supply chains and whether they can sustain these profit margins if spot market prices stabilize or if regulatory changes impact trading on power exchanges.
